I'm designing some furniture that will look like real functional fine furniture on the outside, but will contain 250-280 watts of HPS lamps in the flower furniture, and about 240 watts of flourescents and HPS's in the vegie furniture. I'll be building the furniture from scratch using some classic designs, for example, a Quaker wardrobe, or a farmhouse pine tallboy dresser, or a series of drysinks, or an island highbar/computer center. In the latter furniture, the word "highbar" is appropriate. ha!

Anyway, I'm wondering a couple things about this design/build endeavor.

1) Is there a market for this kind of furniture?

2) How much air flow is required to cool a 70w HPS lamp in a .6cf sealed sheetmetal hood (11"x11"x8"tall) with 4" openings?

I'm planning to use a number of dc computer case fans that are super quiet, because I want the furniture to be silent if possible, but I don't know how many air changes I need for temp/hum control and for lights-cooling. I think 3-5 air changes a minute will work for temp/hum control, and 20-30 air changes a minute in the light hoods will help control heat in the furniture. Anybody beg to differ?

I'm looking at the vegie furniture to have a grow space of 12cf, and the flower furniture grow space is 20cf.

Besides DC fans and controllers for air-cooling the lights and adjusting the temp/humidity of the grow spaces, the furniture will have these other features:

*air-cooled lights, with warm air helping to heat the room
*grow space temperature and humidity regulated by circulating room air through the space when needed, which is determined by sensors.
*grow space exhaust air is filtered (activated charcoal and HEPA filter) and sent to a plenum where it passes through air enriched with ozone and negative ions before exiting the furniture.
*the fan controller allows adjustment of temperature and humidity settings, as well as fan RPMs for either noise control, or air flow control.

I'm also working on an 8' tall brute that will contain both a vegie and a flower chamber. It would look like a big wardrobe on the outside.

All vents will be hidden in the furniture, with fresh air coming up through the bottom on one side, and hot or exhaust air exiting the bottom on the other side. The openings will be hidden behind the cabinet toe boards.

The lights will have a duct system for sealed cooling, and the grow spaces will have a duct system for charcoal filtering and treating exhaust air with negative ion generator and ozone generator in the plenum.

the cabinet sizes have been determined for a dutch SOG perpetual harvest. the vegie chamber will contain four selected mothers, 16 cuttings from the mothers growing roots, and four plants in vegetative growth, chosen from the previous crop of 16 rooted cuttings.

the flower chamber will receive four new 9" tall plants every two weeks, and once it's going, it will also harvest four plants every two weeks. Both chambers are four square feet, so the cuttings are placed into 3" cups and take up one square foot. the mothers take up one square foot. they are in 6" square pots. All the plants, in fact, are in 6" pots. The flower chamber holds 16 plants.

so what do ya think? will anyone buy one of these from me? I realize I will have to make each one and make sure it works, by growing something in them.

I have no idea how to proceed, though. probably ought to find a pot attorney. probably the only people i can sell this furniture to are those who have a marijuana medical permit and want to grow this medicine in the house without all that stink.
